摘　　要：针对桐柏银矿有限责任公司的缓倾斜中厚矿体提出了采用留矿全面法、分区预切顶留矿全面法进行回采,详细介绍了分区预切顶留矿全面法的适宜条件、采准布置、分区及切顶回采作业、安全保障措施和技术经济指标。实践证明该采矿方法具有易于掌握、安全且具有较好的经济效益。Due to the gently inclined thick orebody of Tongbai Silver Limited Liability Company, the shrinkage-comprehensive mining and area-round pre-cut top shrinkage stopping method was proposed. The pre-cut top shrinkage- comprehensive mining method of the optimum conditions, mining preparation layout, area and cut the top stopping operations, security measures as well as technical and economic indicators were described detailedly in this study. The practice shows that the proposed mining method has proved easy to learn, safe and has better economic benefits.
